How to Avoid a Scam Contractor or Fundi in Kenya

A building project or a major home repair puts a fundi, a contractor, or a materials supplier in a position almost nobody else occupies: they take a large payment up front, they control the pace of the work, and by the time something's clearly wrong, you've often already paid for materials, labor, or both. That combination is exactly why construction and renovation scams are so common in Kenya, and why the usual advice (get references, sign a contract) only covers part of the risk. Here's what actually protects you, specific to contractors and the materials they buy on your behalf. ## Verify the materials the contractor is actually using A contractor can be perfectly honest about who they are and still cut corners on what they buy, sometimes without even telling you. This is where the Kenya Bureau of Standards' quality marks matter. KEBS runs a Standardization Mark for products that meet minimum safety and quality requirements, and a separate Diamond Mark, a voluntary mark of excellence that goes further than the baseline standard. For cement, cabling, pipes, roofing sheets, and steel specifically, these marks aren't decoration. They're the difference between materials that meet building code and materials that look fine until the first heavy rain or the first real electrical load. You can check a permit number printed next to a quality mark through the KEBS app, by sending the permit number via SMS to 20023, or by calling the KEBS toll-free line on 1545. It takes a few minutes and it's free. For a project of any real size, ask your contractor which brands and suppliers they're using before work starts, not after the materials are already on site, so you have time to check before it's too late to matter. If you're sourcing materials yourself rather than leaving it entirely to the contractor, a [phone-verified hardware shop](/category/hardware-shops) is a reasonable place to start, since it at least confirms the supplier is a real, reachable business rather than a number that goes dead after the sale. Ask for receipts for every material purchase, even ones the contractor is handling on your behalf, and check that the receipt names the actual supplier rather than just showing a handwritten total. This does two things: it gives you a record of what was actually bought if a dispute ever comes up over quality or quantity, and it makes it much harder for a contractor to quietly substitute a cheaper material than the one you agreed on and pocket the difference. ## Get a written scope before any money moves Verbal agreements are where most contractor disputes start, because "we agreed on X" and "I thought we agreed on Y" are both completely sincere positions once the work doesn't match anyone's expectations. It doesn't need to be a formal legal contract for smaller jobs, but it needs to exist in writing, even as a WhatsApp message both sides can refer back to: what work is being done, which materials, what grade or brand of material, the total price, and the payment schedule tied to specific milestones rather than a single lump sum. That last point is the one that saves the most money in practice. Pay a deposit to secure the booking and cover initial materials, a further portion when the work reaches an agreed stage you can see with your own eyes, and the balance only once you've actually inspected the finished work. A contractor who resists this structure and insists on being paid in full before starting is telling you something about how confident they are that you'll be satisfied with the result. ## Get more than one quote, and be suspicious of the one that's dramatically lower Three quotes for the same scope of work, from three different contractors, tells you roughly where the real market price sits for your job. A bid that comes in far below the other two isn't automatically a scam, since pricing genuinely varies by experience and overhead, but it's worth asking exactly why before you accept it. A common pattern is a low initial quote designed purely to win the job, followed by a string of "unexpected" extra costs once work has started and switching contractors mid-project has become expensive and disruptive. Ask what's included and what isn't, in writing, before comparing numbers against each other. ## Watch for payment requests that don't match how the business actually operates A contractor asking you to send money to a different personal mobile number for every payment, rather than one consistent business line or account, is a pattern worth noticing rather than dismissing as normal flexibility. So is a sudden request to pay a supplier directly, in cash, for materials the contractor was supposed to be sourcing and invoicing themselves. Both are common ways a dishonest contractor spreads a scam across enough transactions and enough names that no single payment looks alarming on its own, and both make it considerably harder to trace the money afterward if something goes wrong. ## Behavior patterns worth watching for Pay attention when a contractor keeps changing the details of the job after you thought they were settled. A quote that grows the moment materials are delivered, a timeline that keeps sliding by "just one more week" without a clear reason, or a scope that quietly shrinks compared to what was discussed are all forms of the same problem: someone managing your expectations downward instead of doing the job that was agreed. Evasive answers about licensing and experience deserve the same direct follow-up as with any business. A fundi doesn't need a university degree to be good at their trade, but a contractor taking on a significant structural, electrical, or plumbing job should be able to point to specific past work you can actually go look at, not just describe. Ask for the address of a completed project, not just photos, and if that request makes them uncomfortable, pay attention to why. Watch for someone who avoids a written schedule entirely, even a loose one, because an open-ended timeline with no milestones is also an open-ended excuse machine. "It'll be done when it's done" sounds relaxed in the moment and becomes expensive three months later. ## Ask around before you ask the contractor Kenyan estate and neighborhood WhatsApp groups, local Facebook groups for specific towns or estates, and even asking a hardware shop owner you trust whether they've heard of a particular contractor can surface a reputation faster than any document search. Contractors who've burned clients before usually have a trail, even if it never reached a police station or a formal review site. Ask directly: "has anyone here worked with this person, and would you use them again?" People are generally more honest in a group chat than they'd be leaving a public review under their own name. Where a business does have a real review history, read the negative ones specifically, not just the star rating. A string of five-star reviews with one detailed complaint about work left unfinished tells you more than the average does on its own, especially if the business never responded to it. ## Ask who's liable if something goes wrong on site Most small Kenyan contractors don't carry formal liability insurance, and most homeowners never ask about it until an accident has already happened. You don't need to turn this into a legal negotiation, but it's worth asking plainly: if a worker is injured on your property, or if the work damages something that wasn't supposed to be touched, who is responsible for that cost? A contractor's honest answer tells you a lot about how seriously they take the job, and in either case, it's worth knowing before work starts rather than discovering the answer the hard way. ## If something's already wrong mid-project Stop future payments immediately rather than hoping the next milestone goes better. Document the current state of the work with photos and a timestamp, in writing, before anything changes. For a registered contractor, the same business registration search that applies to any Kenyan business (through eCitizen's Business Registration Service) lets you confirm who you're actually dealing with, which matters if a dispute ends up in front of a county consumer affairs office or, for larger sums, in court. A written scope and a record of milestone payments, the kind this article recommends setting up from the start, is exactly the evidence that makes a dispute resolvable instead of a stalemate of competing memories. ## What an hour of checking actually saves you Materials verification protects you from quality problems you might not notice for months. A written, milestone-based payment schedule protects you from a contractor who disappears or stalls once they've been paid. Local reputation checks protect you from someone whose history is a warning sign everyone nearby already knows about except you. None of these takes long, and all three are considerably cheaper than redoing a job that was done badly the first time.
